Subject: [PATCH 05/12] netfilter: ebt_ulog: remove unnecessary spin lock protection
Date: Mon, 25 Mar 2013 13:15:45 +0100 [thread overview]
Message-ID: <1364213752-3934-6-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1364213752-3934-1-git-send-email-pablo@netfilter.org>
From: Gao feng <gaofeng@cn.fujitsu.com>
No need for spinlock to protect the netlink skb in the
ebt_ulog_fini path. We are sure there is noone using it
at that stage.
